This level applies to two different work situations. In situation 1), LPN's provide nursing care for patients in various stages of dependency, setting priorities and deadlines for patient care as necessary prior to notifying the supervisor. In situation 2), LPNs are assigned to a selected group of critically ill patients, e.g., in hospital intensive care or coronary care units. These assignments require LPNs to immediately recognize and respond to serious situations, sometimes prior to notifying an RN. However, their overall independence and authority is more limited than that described in situation 1 and supervisory approval is required for proposed deviations from established guidelines.
